(Cl. 683 2) This invention relates to improvements in` wringers or mangles and ythis application is a continuation in parteof an application filed by me on January 8, 1936, Serial No.- 58,075, which has matured into Patent No. 2,073,974, March 16,

The principal objects of the invention are directed to the provision of a wringer which is simple in form and consists of a relatively few parts so as to be economical to manufacture.

This is accomplished by the provision of a novel combination and arrangement of parts.

According to one special feature of the invention the wringer includes a frame structure having operating parts associated therewith and a separable shell or shell parts whereby the appearance of the wringer may be changed or varied without the necessity of changing the mechanial features. In this way the mechanical .features are not limited to or affected by the appearance of the wringer.

Fig. l2 is a perspective view of the end cover or casing for the head end of the wringer.

Referring now to the -drawings more in detailv the invention will be fully described.

The wringerv has a head including a horizontal barrel part 2, a vertical barrel part 4 and an out- Ier end part-|2 which is connected to the head part by a longitudinally extending lower member .|0. 'These parts constitute a support for the wringer and maybe called a frame.

, l" A part indicated generally by 9 extends .upo wardy from and is associated with 4the 'head v which corresponds'to the end part I2. .A bearing, I4 is associated with the vertically extending'tubular part 4 and in this a shaft I6 is rotatable.. This shaft may be driven from a washing ma-., chinemechanism and a. driver in the, form of a. spur gear I8 is fixed on thenupper end of' said shaft I6. ,The part 4 may rest onv the vertical column of a washing machine as is usual with wringers. i

A bushing 20 is rotatable in'a part 2| of the head and thisbushing is bored to receive a shaft 22. The bushing is splined at 24 to receive a key 26-of shaft 22 so that the shaft 22 may recipro-y -cate in and also drive bushing 20.. A pair of gears 26 are rotatable andv reciprocable in a bore 28 of thetubular part 2 of the head. These are of the face type having their teeth on adjacent sides. V

lPins or the like such as 30 secure the gears 26 to shaft 22 so that they reciprocate and rotate therewith. A collar or hub 32 between gears 26 rotatably receives the shaft 22 and a pin 34 is secured to the collar 32 and extends through an angularly disposed slot 35 in the head (see Fig. 10). 'I'he-pin and slot function to bring about reciprocating movements of the collar 32, shaft 22 and gears 26 accordingly as the collar is oscillated. In this way the` g'ears are, shifted or moved from their neutral position vshown in Fig. 5 to an operative engaged 'position with the driver accordingly as the collar is oscillatable in one direction or the other. A shifter is journalled on the part 2| of the head and this has a rearwardly extending part 42 which is slotted at 44 to receive pin 34 (see Fig. l10) and an u'pwardly extending part 4E which is provided with As this part 40 is oscila slot 4 8 (see Fig. 9). lated, the collar 32 is oscillated thereby.

4 A seat or saddle (see Figs. 5 and 8) is associated with the outer frame part `I2 and-a yoke 52 in the form of a L is arranged toseat in the saddle 50. Ajournal part 54 resting in the yoke 52 has a bearing 56 which rotatably receives one'end 53 of the shaft of a lower roll 60. A more or less spherical end 02 of the lower roll shaft`is received in the bushing 20 of the head. A pin 64 thereof is received in slots 66v in the end of bushing 2 0. In this way as shaft 22 rosprings.

52 and other similar ears are associated with thev head (see Fig. 8). Rods 88are slidable in these ears 66' and around these are compression springs 10 which are disposed between'the ears 86' and the heads 12 of bolts 88. Receivers 18 are slidable up and down in the end part i2 and in the head, and the upper vthreaded ends 1| of the rods 68'are in engagement therewith. The receivers 18 in the head end and in the outer frame part I2 are similarly mounted so that the said receivers are spring-pressed downwardly and move upwardly against the action of the The receivers as in Figs. 6 and 8 have on their adjacent faces vertically disposed slots 80. Locks 82 have studs 84 which are journalled in the receivers 16 so that the locks may swing from the neutral position shown in Figs. `6 and 8 to an angular position relative thereto or to an operative locking position wherein they are at an angle relative to the position shown in said Figs. 6 and 8.

'I'he locks' 82 are provided with vertically disposed slots 86 in their adjacent faces and the receivers 16 in their lower sides and on adjacent facesrhave continuations of the vertically disposed slots 80 (see Figs. 6 and 8). The locks 82 which are associated with the head and with the outer frame part I2 are alike except thatthe lock associated with the head has a pin 83 extending rearwardly therefrom. This pin 83 is received in the upper slotted end 46 of the shifter 40 so that as this lock is oscillated, it oscillates the said shifter 40.

A separable upper frame 90 (see Fig. 5). has downwardly extending end parts 82. Projections such as 94 for operating locks 82 extend outwardly from the parts 9l2. An upper wringer roll 96 is preferably journalled, as by bearings 96, on a shaft |00, the opposite ends of which shaft are fixed to the frame parts 62 and extend outwardly therefrom. y

This upper frame 90 and roll 96 constitute a unit which may be withdrawn from and inserted in the wringer. 'Ihe ends of roll shaft |00 and the projections 94 of the frame 90 are receivable in the slots 80 of the Vreceivers and slide into and through slots 86 of the locks' 02, when'the locks are in the neutral inoperative position shown in Figs. 6 and 8.

As before stated, the frame 90 and its associated roll 96 may be withdrawn from or inserted inthe wringer. When inserted in the wringer the upper roll 96 rests on the lower'roll 60 as. shown in Figs. A5 and 7. The ends of shaft |00 vof the upper roll are in the lower part ofthe slots 80 of the receivers 16, while the projections 84 of the upper frame 80 are in the slots 88 of the lock 82. When so arranged in a neutral inoperative position the frame 90 may be swung about the axis of shaft in one direction or 'the other so that the projections- 84 swing the locks 82 into locking position. In locking position locks 82 are disposed so that grooves 88 thereof are at an angle relative' to the position shown in Figs. 6 and 8. The lower ends of the slots' 86 instead of being over shaft |00 are at .a side thereof and their lower edges 85 ridevonto the` ends of shaft |00 locking the frame 80 and roll 88 to the spring-pressed receivers.

Prior to swinging frame 90 from inoperative to'an operative position, it must be released because it is releasably locked in its inoperative,

neutral position. To accomplish this the following is provided.

Y' A lock bar |00 (see Figs. 5, 6 and 7) has a l forward end |02 which is receivable in the vertical siot 80 of the receiver 18 at the head end of the wringer. A lever |08 pivoted at ||0 to frame 90, has a forward end ||2 and a rear end ||4. A rod |04 slidable up and down in the frame 90 carries a manually engageable part or button |08. 'Ihe lower end of rod |04 rests on the part ||2 of lever |08 and a spring H6 seated in the frame 90, as shown, bears on the outer end of the lever |08 and tends to urge the said pressed to swing lever |08 and withdraw the forward end 02 of the lock bar from the slot.

' This permits the frame to be swung in one direction or the other.

When the frame 90 is swung from an operative position to an inoperative position and arrives at its neutral inoperative position the lock bar |00' slides forwardly into the slot to releasably lock the frame 90 in neutral inoperative position. As stated, when the wringer frame 90 is in an operative position and the locks have been swung thereby to locking position the lower edges 85 of the locks 82 ride up on the ends of the lshaft |00 of the upper roll so as to lock the upper roll against the lower roll and then asthe upper roll moves away from the lower roll it acts against the springs so that the material being passed through the rolls is subject to the action of the springs.

`As previously stated, the head part of the wringer is adapted to rest on a washing machine part such as the column thereof. It is usual that the wringer be rotatable but it is desirable that it be rotated only when the wringer rolls are inoperative. To that end the following is provided.

As shown in Figs. 5, 9 and 11 a lever |40 is xed to shafts |42 which are journalled in the head and carry manually engageable handles or levers |44. On the forward end of the lever |40 there is a projection |46. 'I'he lever |40 in its lower position rests on ledge |54. -A detent |48 isslid- .able up and down in the head as shown in Fig. 1 and it extends upwardly through the lever |40 with a head end |52 on top of said lever.v A spring |50 around the detent urges the-said detent downwardly. This detent is adapted to enter a socket or sockets of a column which'supports the wringer for locking the wringer against swinging.

A lower part 4| of the shifter 40 has a slot or notch |48 for receivinglthe projection |48 of` lever |40. When the lever 40 is in an inoperative neutralv position, the notch |48 thereof overlies the projection |48 so that the lever |40 may now be swung upwardly to move the detent |48 from locking position. When the wringer is in operation the lever 40 has its part 4| toone side of .the position shown in Fig. 1 when the lever |40 may not be elevated since the projection brings up against the lower end of part 4|. This is desirable 'as it prevents lthe wringer being'swung while the rolls are in operation,

As a feature to facilitate the ready and easy assembling of the-parts the member 40 is maintained in'position for oscillation in-the head in the following manner (see Figs. 5 and 9).

A slot |60 is provided in the hub of the shifter. 40 which when the said part 40 is swung counterclockwise from the position shown in Fig. `9 allows the opening |60 to register with an opening in the bearing part 2| of the head. In this position a lock in the form of a ball |62 is dropped through the opening |60 in part 40 into the opening in said bearing part 2|. 'I'hen when the part 40 is swung clockwise, the opening |60 is out of register with the ball |82 so that it cannot become displaced. The part 40 is recessed at |64 and the part 20-,is provided with an annular` groove |66. These permit oscillation of the part Y ends which are seated on lugs |34 oi longitudinal member |0 and a projecting part |34 on`oscillatable member 40 engages the head end of the drain board so that the drain board is tilted to an inclined position by the member 40. Extensions are provided at the sides of drain board I0.

The features of the wringer of the invention already described pertain to the mechanical con.. struction thereof as well as its operation and according to this invention the ornamental appearance of the wringer is dependent on certain Vparts associated with the parts described. Therefore certain outer ornamental parts are provided which may be varied to vary the appearance of the -wringer without changing its mechanical structure. This is very desirable as it is necessary to change the appearance of wringers frequently but the ornamental appearance is in no way affected by the mechanical construction.

To this end casings such as |16 in Fig. 12 and |80 in Figs-1 to 3 are provided. These are different in appearance but are arranged to fit over the head. These casings are preferably of sheet metal or they may be made as a casting or by a stamping, pressing or-other operation. As shown in Fig. 12, the casing has side walls |12, rear wall |14, upper wall |16' and a hoodpart |18. The side walls |12 at their forward sides are arranged to fit on members |16 of the head and openings such as |11 are provided for screws for fastening the casing to the head. The casing as in Fig. 5 may have aboss |19 which fits in theend of the horizontal bore 28 ofthe head. This is to centralize and position the casing.

For opposite sides of the wringer there are side parts |82 such as shown in Figs. 1 to 4 inclusive.

These have end portions |84 and a horizontally disposed portion |86. These members |82 are vpreferably of sheet metal or th like so as to be these bolts |02 are passed. These bolts secure ythe side parts |82 to the wringer and of course may take various forms.

While -I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes andA modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim' and secure by Letters Patent of the United States is:
